Under-fire Rangers boss Graeme Murty says he has received plenty of backing since his Old Firm disaster — but has heard nothing from chairman Dave King.

The former academy coach’s hopes of clinging on to his job beyond the summer appear all but over after last Sunday’s 4-0 drubbing by Celtic in the William Hill Scottish Cup semi-final.

Yet he will remain in charge for Gers’ final five league games, starting with tomorrow’s showdown with Hearts at Ibrox.

While he will have to face the music in front of the disgruntled Light Blues faithful, chairman King is still in South Africa and has yet to address the growing number of fans now questioning his leadership.

And neither has he picked up the phone to offer support to a man who has twice stepped in to act as caretaker boss during times of crisis.

Murty said: “If I can get through this week, I can get through just about anything.

“I’ve had lots of support. I’ve had the director of football, my entire staff and the board of directors making sure I’m okay and ready to go for this weekend.

“They’ve been fantastic in making sure I get what I need and I’m ready to go. But no, I haven’t spoken to the chairman.”

Murty admits it has been a tortured week for himself and his squad as they try to recover from that crushing defeat.

The manager has not escaped the wrath of the Ibrox support, who have hit out at his team selection and tactics. But the 43-year-old has vowed to learn from his mistakes.

“We didn’t do the club or ourselves justice,” he said.

“There was potential for the guys on the pitch to do better than they did.

“We didn’t turn up to the extent that we could and were punished accordingly. That hurts.

“If I look back on it, there are things I’d do differently. I feel I’m learning in the most public environment you could imagine.

“I’ll make mistakes very publicly but I’ll learn from them quickly and improve.

“There were lots of things we needed to do better — myself and the players — to represent ourselves in a better manner, because we were guilty of letting a lot of people down.”
